Specification of Letters Patent.

Patented Jan. 19, 1909.

Application filed April 30, 1908. Serial No. 430,095.

To all whom it may concern:

Be it known that we, TIMOTHY A. HAR- RINGTON and ALEXANDER BARRm, citizens of the United States, residing at Natick, in the county of Kent and State of Rho de Island, have invented a new and useful Improvement in Spinning-Viachines, of which the following is a specification.

This invention has reference to an improvement in spinning machines and more particularly to an improvement in mechanism adapted to automatically remove waste, fiber, or lint from the arts of a spinning machine most difficult of access and most liable to i have the same deposited thereon.

that the lint, waste, or fine fiber which col lects on the machine is at times drawn onto the yarn, on which it forms knots, enlargements or bunches, thereby producing a yarn with imperfections or an inferior quality of yarn.

The object of our invention is to provide a spinning machine with mechanism adapted to automatically clean and remove the lint or loose fiber from the roller beam, thread board, finger boards and the adjacent portions of the top board, weight wires and roller stands of the machine.

A further object of our invention is to construct an automatic cleaner mechanism for spinning machines so that the mechanism will be positive in its operation and operatively connected with and easily attached to the existing forms of spinning machines.

Our invention consists in the peculiar and novel construction of an automatic cleaner mechanism for spinning machines, said mechanism having a positive automatic reverse gear motion, reciprocating cleaner blocks, means for operatively connecting the mechanism with the running mechanism of the machine, and details of construction, as will be more fully set forth hereinafter and claimed.

Figure 1 is a top plan view of the front portion of a spinning machine, showing the central portion and the roller stands broken away and the machine provided with an improved automatic lint or fiber cleaner mechanism. Fig. 2 is a front elevation of Fig. 1, showing the front of the reverse motion and the position it Would assume when operated by the front cleaner block to move the front cleaner block toward the opposite end ofthe machine. Fig. 3 is an enlarged vertical sectional view taken on line 3 3 of Fig. 1, looking at the back of the reverse motion. Fig. i is an enlarged vertical sectional view taken on line 4 4 of Fig. 3, showing the reverse gear and operating levers. Fig. 5 is an enlarged horizontal sectional view taken on line 5 5 of Fig. 3, showing the cam hub and the reversing levers. Fig. 6 is an enlarged detail view of the operating end of the front reversing lever. Fig. 7 is an enlarged detail view of the operating end of the back reversing lever, and Fig. 8 is an enlarged detail sectional view taken lengthwise through one of the cleaner blocks and showing the pockets in the same for collecting the waste or lint.

In the drawings, a and b indicate the end frames, c the top board, (1 the roller beam, e the thread board, ff the finger boards, 9 g the roller stands, and h h the weight wires of a spinning machine provided with our improved automatic cleaner mechanism which consists of a horizontal shaft 9 rotatably supported in bearings 1 1 11 formed integral with a bracket 10 secured to the front of the roller beam cl, as shown in Figs. 2 and 3. This bracket 10 has, in addition to the oppositelydisposed bearings 11 11 the downwardly-extending arms 12 12 on the front and back in each of which is a horizontal slot 13 on a line with the shaft 9 and the vertical bearings 14 14, as shown in Figs. 3 and 4. A pulley 15 is secured to the shaft 9 adjacent the outer bearing 11. A cam hub 16, having an annular cam groove 17 in its periphery at an angle to the axis of the hub and oppositely-disposed bevel gears 18 and 19 on'each end, is splined to the shaft 9 intermediate the bearings 11 11, revolves with the shaft and is adapted to have a reciprocating movement on the shaft, as shown in Fig. 5. A reverse gear lever 20 having the semi-circular central portion 21, the outwardlyextending end 22, and the rearwardly-extending end 23 is held with the central portion 21 in its operative position in the cam groove 17 with the end 22 extending through the slot 13 in the front arm 12 and the end 23 extending through the slot 13 in the back arm 12. By this construction, on revolving the cam hub 16 the ends of the reverse gear lever 20 are given a predetermined horizontal reciprocating motion, as shown in full and broken lines in Fig. 5. A bracket 24 of the required form is secured to the front of the roller beam 01 adjacent the bracket 10, as shown in Figs. 2 and 3. A front horizontal reversing lever 25 having the hook-shaped end 26 and the straight end'27 is pivotally secured adjacent the end 27 to the bracket 24 in a position for the hook-shaped end- 26 to engage with the end 2 of the reverse gear lever 20, as shown in Figs. 2 and 5. A back horizontal reversing lever 28 having the shouldered end 29 and the straight end 30 is pivotally secured adjacent the straight end 30 to the bracket 24 in a position for the shouldered end 29 to engage with the end 23 of the reverse gear lever 20, as shown in Figs. 3 and 5. A front vertical operating lever 31 having the upper end 32 and the lower end 33, is secured to a rock shaft 34 in a position for the upper end 32 to extend upward on the front of the roller beam d and above the same into the path of the front cleaner block 51 and for the lower end 33 to engage with the end 27 of the front reversing lever 25, as shown in Figs. 2 and 3. The rock shaft 34 is supported in a bearing 35 on the bracket 24, and a segmental gear 36 is secured to the inner end of the rock shaft 34. A back, vertical operating lever 37 having the upper end 38, the segmental gear 39, and the lower end 40, is pivotally secured through the segmental gear 39 to the bracket 24 in a position for the upper end 38 to extend upward through a slot in the roller beam 1 into the path of the back cleaner block 54, for the segmental gear 39 to mesh with the segmental gear 36 and for the lower end 40 to engage with the end 30 of the back reversing lever 28, as shown in Figs. 3 and 5. A vertical shaft 41 is rotatably supported in the bearings 14 14 and has a bevel gear 42 on its lower end, intermediate the bevel gears 18 and 19 and in a position for the gears 18 and 19 to alternately mesh with the same. The vertical shaft 41 ex tends upward through a hole in the roller beam (1 and has a grooved pulley 43 and disk 44 secured on its upper end. A series of brushes 45 45 extend downward from the disk 44 to approximately a line with the un derside of the pulley. A similar grooved pul ley 46 and a disk 44 with the brushes 45 45 are rotatably supported in a bearing 47 which is adj ustably secured in a bracket 48 fastened to the end frame 6, as shown in Figs. 1 and By turning a screw 49 (in the bracket 43) which is in screw-thread engagement with the bearing 47, the pulley 46 may be ad.- justed toward or away from the pulley 43..

The pulleys 43 and 46 which are at opposite ends of the machine on a line with the roller stands 9- g are connected by an endless cord 50 to which is secured a front cleaner block 51 supported on the thread and finger boards 0 and f f and having the inverted pockets 52 52 at each end and its under surface between the pockets covered with felt 53 or a similar material, as shown in Fig. 8. A back cleaner block 54 similar to the front cleaner block 51 is secured to the cord 50 back of the roller stands and rests on the to board 0 and roller beam (1. This cleaner b ock 54 has in addition to the pockets 52 52 and the felt 53, the brushes 55 55 placed at each side of the block in a position to brush the lint or fiber from the roller stand supports, the weight wires, and the upper surface of the top board androller beam. The cleaner blocks are secured to the cord in a position for the blocks to pass each other at a point centrally between the pulleys 43 and 46.

In the operation of our improved cleaner mechanism for spinning machines, the pulley 15 is connected by a belt to a pulley in the driving mechanism of the machine (not shown) and is revolved in the direction of the arrow, as shown in Fig. 3. The reverse gear lever 20 through the cam hub 16 is given a constant horizontal reciprocating motion, as shown in full and broken lines in Fig. 5. The reverse mechanism is shown in the position it would assume when reversed by the front cleaner block 51. Power from the pulley 15 is transmitted through the shaft 9, the bevel gear 18, the bevel gear 42, the vertical shaft 41, the pulley 43 and the cord 50 to draw the front cleaner block 51 toward the end frame I) and to draw the back cleaner block 54 toward the end frame a when the block 54 engages with and moves the end 38 of the back operating lever 37 out of its vertical position toward the end frame a. This releases the back reversing lever 28 and allows the shouldered end 29 of the lever to drop by gravity into a position to engage with the rearwardly-extending end 23 of the reverse gear lever 20. On the next revolution of the cam hub 16 the end 23 of the reverse gear lever 20 engages with the shouldered end 29 of the reversing lever 28 and through the operation of the cam hub 16 on the reverse gear lever 20 moves the bevel gear 18 out of mesh with the bevel gear 42 and the bevel gear 19 into mesh with the bevel gear 42, thus reversing the motion of the pulleys 43 and 46 and the cleaner blocks, which now move in the reverse direction the length of the machine until the front cleaner block 51 engages with and moves the end 32 of the front operating lever 31 out of its 7 shaped end 26 of the reversing lever 25 and through the cam hub 16 and lever 20 moves the bevel gear 19 out of mesh with the bevel gear 42 and the bevel gear 18 into mesh with the bevel gear 42 when the cleaner mechanism is again reversed into the position, as shown in Figs. 1, 2 and 3. If through the vibration of the machine or other causes the bevel gears 18 or 19 should get out of mesh with the bevel gear 42 the next reciprocating movement of the reverse gear lever 20 will force the gear, which should be in o eration, into mesh again. The movement of the end 32 of the front operating lever 81 toward the end frame a or out of its vertical position, moves the back operating lever 37 into'its vertical position through the rock shaft 34 and the segmental gears 36 and 39, and tne lower end 40 of the back operating lever engaging with the straight end 30 of the back reversing lever 28, raises the shouldered end 29 of the back reversing lever out of the path of the reciprocating end 23 of the reverse gear lever 20, as shown in Fig. 3 and vice versa. The cleaner blocks in traversing the length of the machine remove the waste, lint or fiber from the roller beam, thread board, finger boards, and the adjacent portions of the top board, weight wires and roller stands of the machine and collect the same in the inverted pockets 52 52 of the cleaner blades 51 and 54, from which it is easily removed from time to time by the operator. The circular motion of the brushes 45 45 over the cord 50 tends to keep the cord free from lint or'fiber.

It is evident that both sides of a spinning machine may be provided with cleaner blocks operated from one automatic reverse motion mechanism without materially afiecting the spirit of our invention.

Having thus described our invention, we claim as new and desire to secure by Letters Patent 1.
